I spun a rod bearing on my 2.3l duratec because it burned through most of the oil in less that 3000 miles. My parents got it new and took pretty good care of it, but it always burned some oil, probably because it wasn't broken in right. I have since replaced it with a reman and it burns 0 oil and runs perfectly. Just check your oil every time you get gas and top it off if it needs it and you will be good to go!
